So far, no. The Wasabi team has released a firmware upgrade (2.0b), which is installed from DVD, and which enhances the functionality of the chip (most noticably it makes it possible to use the Wasabi DX as a Wasabi Zero if you don't have one of the epoxy Wii drive chips). Otherwise it's more a safety thing in case the big N makes a future update to the Wii System Menu, which requires an update of the modchip.

Yes... Like most other modchips the Wasabi DX chip has a built-in out-of-region update blocker, in order to prevent your Wii from bricking.

SSBB runs fine. But there is problems with choppy video/audio in the cutscenes in Super Mario Galaxy and WarioWare: Smooth Moves.

Just a piece of advice: Check first what version of the Wii drive chip you have. If you have the epoxy type, Wasabi DX is probably your best choice, unless you want to softmod your Wii. If you have one of the older Wii drive chips without epoxy, you are probably better off with a traditional soldered modchip (can be installed via a Wii clip, if you like). The latter types of modchips don't have the choppy video/audio issues as they run at 6x speed (at least most of them do).
